Mizoram , India -LRB- CNN -RRB- -- The world 's population hits 7 billion this week , but Ziona , the patriarch of what may be the biggest family in the world , is not bothered .

`` I do n't care about overpopulation in India ... I believe God has chosen us to be like this -LRB- have big families -RRB- . Those who are born into this family do n't want to leave this tradition so we just keep growing and growing , '' he says with a smile .

Ziona , who only goes by his first name , has 39 wives , 86 children and 35 grandchildren .

Ziona 's father , Chana , founded the Christian sect in Baktwang village that promotes polygamy as God 's will . `` I never wanted to get married but that 's the path God has chosen for me , '' he says . `` It 's not my wish to keep marrying again and again . ''

All 160 family members live in a four-storey mansion perched on top of a remote village in the northeastern Indian state of Mizoram .

The state , neighboring Myanmar and Bangladesh , has one million residents , one of the lowest population densities in this country of 1.2 billion . Despite its natural beauty , special permits are required to enter the state , making tourism virtually non-existent .

Four hours away from Mizoram 's only airport , in the isolated village of Baktwang , Ziona 's bright purple house with 22 bedrooms stands out .

The main room is a giant hall where the family cooks , eats and prays . The bedrooms are dormitory-style with an average of 20 beds , each double bed about a foot apart from the next . The children sleep with their mothers who take turns visiting the 69 year-old 's master bedroom .

`` There is no discrimination amongst us , he treats us all equally , '' fifth wife Twangi says .

Ziona first got married when he was 17 to Zathiangi , who is now 70 . His youngest wife is 31 .

As the eldest wife , Zathiangi calls all the shots in the kitchen so meal times are an efficient exercise .

Without much fuss , while some women of the house cook , others set the table , still others serve and clean .

`` We cook 25 kilograms of rice , 40 kilograms of potatoes and 5 kilograms of lentils everyday , '' Twangi says .

The family indulges in meat three times a week and for every non-vegetarian meal , 30 chickens are plucked and a giant pig is roasted .

But the sheer volume of food that needs to be cooked or plates that need to be washed does n't overwhelm the women of the house .

Like a well-oiled machine , everyone carries out their individual chore , so dinner for 160 is ready within an hour and utensils are washed and put away within minutes .

Even the children help out . Tiny 6-year-olds have become experts at plucking chickens , and everyone seems to get along .

`` No fighting , never , we are all one family , there 's no other people here so we do n't fight , '' says sixth grandson Hmingthamzauva , one of the few in the household who speaks English .

`` Since we are used to living in a very big family when we go outside to study we actually feel very lonely , '' he says laughing .

But while he likes living in a big family , he himself does n't want more than one wife .

`` My grandfather is specially appointed by God to have as many wives as possible and to look after them . But for me , having one wife and one son is quite enough . There is no rule or tradition as such that we have to follow polygamy , for me it 's actually unbearable , '' Hmingtahmzauva says .

Hmingtahmzauva says his great grandfather Chana , who also had multiple wives , had a spiritual revelation after he was expelled from the Catholic Church for his unusual lifestyle .

So Chana created his own polygamist sect , which now has a following of 400 families .

Ziona is the caretaker of the self-reliant sect . They grow their own crops and raise their own livestock .

`` Everyone has a designated job . Some are doing carpentry work , some take care of the piggery and poultry farm and others cultivate crops , '' Ziona says .

He has set up a school nearby for children of the community , the curriculum comes from the government but Ziona has added some sect-specific teachings .

`` My father is the greatest god that we can have in this world , he has done so much for us , '' says his eldest son Nunparliana , who has two wives and 14 children .

India is set to overtake China as the world 's most populous nation by 2030 . But crowding and crumbling infrastructure in India 's booming cities do n't faze Ziona .

`` I 'm not troubled by the noise or the overcrowding . My mind remains at peace , '' he says .

The family is not listed in the Guinness Book of World Records because Ziona says he does n't want the publicity . But as word gets out , Baktwang village and Ziona 's family may not remain so isolated .
